METHOD OF TRANSMITTING INFORMATION IN A COMMUNICATION SYSTEM WITH BROADBAND SIGNALS Russian patent published in 2019 - IPC H04B7/216 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to radio engineering, particularly to information processing systems using complex broadband signals and can be used in broadband interference-free radio communication systems. Proposed method consists in generation of carrier and clock signals on transmitting side, generation of five phased binary pseudorandom sequences from clock frequency signal: synchronizing sequence (SS), three identical information sequences (IS) and auxiliary sequence (AS), wherein IS are transformed by cyclic shift relative to SS by integer numbers of cycles defined by three information symbols, and modulo addition of two with three additional bits of information, transformed IS modulo two with AS, obtained three sequences are majority-folded with phase-shifted carrier frequency signal, phase-shifted through 90°, obtained signal is folded with SS, phase-manipulated by carrier frequency signal, further amplified and transmitted over a communication channel, on the receiving side, the signal is amplified and frequency-converted, a clock frequency signal is generated, from which SS, IS and AS phased ones are formed, SS are phased with the received signal, the input signal amplified and frequency-converted is supplied to three identical reception channels, in one of which it is manipulated in phase of the first AS, and in the other two – second and third AS, then in each channel determining cyclic shift IS relative to SS, as well as availability of inversion IS, from which the received information symbols and their additional bits are determined.

EFFECT: high speed of transmitting information.
